Description
United States Patent i Chemical Company, Midland, Mich, a corporation of Delaware N0 Drawing. Filed Jan. 25, 1961, Ser. No. 84,773 Claims. (Cl. 260-4295) This invention relates to a new class of chemical compounds and to a method of their preparation, the compounds being characterized as organo metal salts of organo metal chelates of ethylene dinitrilo tetraacetic acid and polyamino polyacetic acids.
For many purposes it is essential to have certain metals in organic form wherein the metal can be made available for its biological activity. For example for many pur poses metal chelates are useful biologically in that the chelatcd metal provides a reservoir of that metal ion for the physiological system into which it is passed, or it can be exchanged for another metal in the system and thus be useful, for example, in detoxification operations. In this connection reference may be had to United States Patent 2,698,823, Bersworth and Rubin. Quite often it is desirable that the metal chelate added to a biological system also carry additional organo groups which can contribute to its usefulness without impairing biological activity or possibly while enhancing the biological activity of the compound.
It is, accordingly, a fundamental object of this invention to provide organo tin compounds characterized by their being chelates of certain amino acids which chelates will also carry other organo metal groups rendering the compounds useful in organic systems.
It is another object of the invention to provide tetra substituted organo tin compounds carrying four functional groups any one of which may be modified to alter the properties of the tin compounds.
Other objects and advantages of the invention will in part be obvious'and in part appear hereinafter.
This invention accordingly is embodied in a new kind of chemical compound which is a novel salt of fully substituted organo metal and may be characterized essentially as a salt of organo substituted metal formed with a chelating agent, wherein the chelating portion of the molecule is fully occupied by additional organo metal moiety. More specifically the structure of the composition may be shown in conventional fashion by the following representation:
wherein the R represents the organo constituents alike or different on the metal. Me and Me represent the metal which could be the same or different, Me being chelates and Me being a part of the salt; and X represents the chelating moiety of the molecule; n is an integer which is large enough to satisfy the valence of Me m is an integer and is large enough to satisfy the X moiety; 0 may be 0, as when Me is divalent, but generally has a positive value which satisfies the valence of Me More specifically these compounds may take the form of his trivinyl tin salt of the diphenyl tin chelate of ethylene dinitrilo tetra acetic acid, which is represented by the following formula:
3,117,147 Patented Jan. 7, 1954 From the example it will be seen that the organo substitution of the tin, which is in the salt forming portion of molecule, may be an unsaturated group, such as a vinyl group, or further that the organo group of the tin atom may be a phenyl group, or it may be any other more or less reactive group. In the example given tin carries both, i.e., unsaturated moieties in one position, the other moieties in the other.
With a molecule of this structure it will be seen that functionality appears in several places and that it can take the form of unsaturation suitable for reaction with polymer forming materials, or for direct polymerization, and further the molecule can be used as the carrier of other groups.
The structure of the compounds leads to a number of advantages in that the points of variability introduce the possibility of making the compound very specific biologically, or very broadly active as an insecticide, bactericide, herbicide or parasiticide. The compound offers so many sites for the inclusion of chemical moieties and combinations of moieties that tailor made specific insecticides become possible.
Typical compounds which can be made in accordance with this invention are the following:
Bis (trivinyl tin) salt of the diphenyl tin chelate of EDTA Bis (triphenyl tin) salt of the diphenyl tin chelate of EDTA Bis (tributyl tin) salt of the diphenyl tin chelate of EDTA Bis (trivinyl tin) salt of the diphenyl lead chelate of EDTA Bis (trivinyl tin) salt of the tin (II) chelate of EDTA Tin (II) salt of the divinyl tin chelate of EDTA The organo metal portions of the compound is best exemplified by organo tin salts which are readily available commercially as hydroxides, halides, acetates or his organo oxides having at least the following in the strucan accurate indication of the manipulations involved in the formation of each compound.
Example I Bis-trivinyl tin salt of di-phenyl tin ethylenediaminetetraacetic acid. I
1 millimole of bis-trivinyl tin EDTA and 1 millimole of di-phenyl tin dichloride are slightly heated in milliliters of acetone. A few drops of water are added until the reactants are dissolved. By adding a large excessof Water, the compound precipitates, is filtered off and air dried.
II: Two millimoles of trivinyl tin hydroxide are added to 1 millimole of divinyl tin EDTA (chelate) in 100 ml. of 60 ethanol in Water. The reactants dissolve completely and after addition of excess ethanol the bis (trivinyl tin) salt of the divinyl tin chelate of EDTA precipitates. The crystals are filtered off and dried by suction.
III: One millimole of stannous chloride dissolved in a small volume of ethanol is added slowly to one millimole of the divinyl tin (IV) chelate of EDTA in approximately 100 ml. water. The pH is kept between 5 and 7 by addition of sodium hydroxide. The reactants dissolve completely and the tin (II) salt of the divinyl tin (IV) chelate of EDTA is precipitated through addition of ethanol.
IV: Substitution in Example III of the his (trivinyl tin 3 (IV)) salt of EDTA for the divinyl tin (IV) chelate of EDTA results in formation of the bis (trivinyl tin (IV)) salt of'the'monotin (II) chelate of EDTA.
